How to get a preview of a CON file?

My friend wants to use the in game notes to help learn songs on his acoustic drum set. Is it possible to take an already created CON file and use REAPER or MAGMA to just look at the drum part with cymbals?

The easiest way is to use CPlayer the load the con and simply view the expert charts for all instruments in real time (like playing RB). You can search the forums for a link to CPlayer I believe.

You can also extract the midi from the con file. Load C3 Con Tools and drag the con file onto the window. Then browse through the con file structure and you can extract the midi and the audio and load them into reaper. If the audio is encrypted you will need to provide your own file and line it up with the midi in reaper.

I was looking for the exact same thing (wanting to play along with customs on my acoustic kit) and Rok Drummer was the perfect solution for me. Super easy to get up and running and a great way to play along with the expert chart. Thank you TrojanNemo!
